Abstract: A picture display controller can display picture data taken from a plurality of viewpoints in a flexible manner. For displaying moving-picture data taken from the plurality of viewpoints, read from a storage medium or received from a server, switching can be made at any time between a manual mode in which a picture is selected or synthesized based on designated information such as viewpoint position included in a viewpoint setting command from the controller operated by the user or from the sensor such as head tracker and displayed and a preset mode in which moving-picture data taken from different viewpoints are selected one after another according to a picture display program preset for a moving picture and displayed. With this system design, a user's setting can be made effective only for a picture portion in which he is interested.

Abstract: A system for assisting in management of a packaging plant, according to which such information as on packaging cost, machine characteristics and surface packaging method is transformed into database, whereby the packaging cost calculation, production capacity calculation, line arrangement method, packaging method, and packaging arrangement investigation method are translated into numeral equations or software. With this system, highly accurate investigation results can be output in a short time period, thereby assisting in making an optimum management decision.

Abstract: A production system for mounting components on circuit boards includes a solder printing unit having a solder printing device for printing solder onto lands of a circuit board and a solder printing inspecting device for inspecting a printing state the solder, a component mounting unit having a component mounting device for mounting a component to a predetermined position of the printed solder on the circuit board and a component mounting inspecting device for inspecting a mounting state of the component, and a soldering unit having a soldering device for melting and hardening the printed solder and a soldering inspecting device for inspecting a soldering state of the soldering.

Abstract: An assembly line includes a printing device for printing solder on a land of a circuit board, a mounting device for mounting an electric component at a predetermined position of the solder, and a soldering device for soldering the land to a terminal of the component. A monitored items detecting device detects predetermined to be monitored items of the board and equipment used in the printing, mounting, or soldering devices, and a control device analyzes a condition of the equipment and quality of the board with reference to warning criterion which do not exceed failure criterion, and then dynamically controls the various devices accordingly.
